如何在Python 3中删除字符串中的特殊字符？

Question

I would like to convert

from this

<b><i><u>Charming boutique selling trendy casual & dressy apparel for women, some plus sized items, swimwear, shoes & jewelry.</u></i></b>

to this

Charming boutique selling trendy casual dressy apparel for women, some plus sized items, swimwear, shoes jewelry.

I'm very confused how to remove not only special characters but also some alphabets between the special characters. Can anyone suggest a way to do that?

Answer 1

Try the following:

import re

string = '<b><i><u>Charming boutique selling trendy casual & dressy apparel for women, some plus sized items, swimwear, shoes & jewelry.</u></i></b>'

string = re.sub('</?[a-z]+>', '', string)
string = string.replace('&', '&')

print(string)  # prints 'Charming boutique selling trendy casual & dressy apparel for women, some plus sized items, swimwear, shoes & jewelry.'

Your string that you want to change looks like it was HTML that's been escaped a few times over, so my solution only works for that kind of thing.

I used regex to replace the tags with empty strings, and also I replaced the escape for an ampersand with a literal & .

Hopefully this is what you're looking for, let me know if you have any troubles.

Answer 2

You can use html module and BeautifulSoup to get text without escaped tags:

s = "<b><i><u>Charming boutique selling trendy casual & dressy apparel for women, some plus sized items, swimwear, shoes & jewelry.</u></i></b>"

from bs4 import BeautifulSoup
from html import unescape

soup = BeautifulSoup(unescape(s), 'lxml')
print(soup.text)

Prints:

Charming boutique selling trendy casual & dressy apparel for women, some plus sized items, swimwear, shoes & jewelry.
